' UNITED PATENT OF E- ALEXANDER sAxE, or new YORK, N. Y.

TOOTHIBRUSH: j

Application filed October 20, 1525. Serial No. 63,573.

The device, the subject. of this invention, is a tooth brush having a detachable handle. The object of this invention is to provide a tooth brush, wherein the handle is in rotatable relation to the head and wherein the head may be removed from the handle or holding member and a new head substituted.

A further object of the invention is to construct a tooth brush in such a manner that if? the handle maybe made of precious or semiprecious metals or materials and may be used for a long period of time, new heads or bristle carrying parts being substituted whenever desired, just as razor blades are substituted in safety razors.

A further object of the invention is to encarrying parts, which may be discarded at no great expense and a further object of the invention is to construct a brush fulfilling the objects above set forth and yet of such simple construction and operation that it may be successfully used by even those entirely lacking mechanical knowledge.

With these and other objects in view, the following is what I consider a good means of carrying out this invention and the accompanying drawing should be referred to for a complete understanding of the specifi cation which follows In the drawing Fig. 1, is a side elevation of-my' device assembled.

Fig. 2, is a top plan view.

Fig. 3, a sectional view on the line 33 in Fig. 2.

Fig. 4, is an enlarged view of a portion of the handle.

F ig- 5, an enlarged view of the clip or head holding part.

Fig. 6, is atop plan view of the bristle carryin head.

Simi ar reference numerals indicate like parts in all the figures where they appear.

' The handle of my device, may, as shown in i the drawing, be formed of two parts, as in dicated at 10 and 11. more or less than a grip member and may be of hollow metal, of celluloid or other suitable material. The part 11 is the shank member and should be of steel, bent as shown at 12 and I prefer that the angle of bend should be about that shown." The portion 13 of the blade 11 is flattened and is provided with a perforation as shown at 14in Fig. 4, and adjacent to this perforation is a downward projection as shown at 15 in Fig.

4, this projection being formed integral with the shank'member and forcing the metal of downward.

Through the perforation 1 1, a rivet 16 is itmay be formed by the shank member The part 10 isnothing passed. The rivet passing through the member shown in Fig. 5 and whichI will refer to is the clip 17 This clip is a strip of preferably spring steel, provided, with two inward projections as shown at 18 and 19 in Fig.3. This clip is also provided with a perforation 20, a part of the wall of which is cut away to forman are shaped recess 21,

as shown in Fig. 5 and in which the projection 15 will operate.

The head of the brush is provided at its mid-length with a shallow recess 22, which extends not only across the top of the head but down the sides thereof to a limited extent. The depth of the recess is approximately equal to the thickness of the metal from which the clip 17 is formed andI may provide a shallow annular recess 23 at midcenter of the head 24, which will receive the head portion of the rivet 16. The rivet 16 secures the shank l3 and clip 17 firmly to-- gether, care being taken that these parts be so securedthat they will not turn easily, one on the other, thus avoiding accidental displacement of the parts.

The operation of my device may be well understood from the description and its construction. Attention is called to the fact, however, that when the parts are assembled as described, the handle member may be partially rotated out of the right angled or transverse position, shown in Fig. 2, to a position approximately that of the dotted lines 25 and the position at the other side of the center or right angled position will be equal to that shown by the dotted lines 25.

Having carefully and fully described my invention, What I. claim and desire to obtain is z A tooth brush comprising a brush head provided with an indent at each side thereof,

a spring clip having up-set projections adapted to engage in said indents, said clip being provided with a sector shaped perforation and ahandle connected to said clip ALEXANDERQSAXE.
